Description

本発明は、接続金具に関する。さらに詳しくは、天井スラブと天井下地材との間で傾斜して設けられるブレースと前記天井下地材とを接続する接続金具に関する。 The present invention relates to a connection fitting. More specifically, the present invention relates to a connection fitting for connecting a brace provided to be inclined between a ceiling slab and a ceiling base material and the ceiling base material.

従来より天井下地構造として、例えば特許文献１（図１６）に示す如きものが知られている。この天井では、天井スラブから垂下する吊材に介在させた防振ハンガーにより振動（音）の伝播を抑制すると共に、天井スラブと天井下地材との間で傾斜して設けたブレースにより地震等によって生じる天井の揺れを抑制している。しかし、ブレースは吊材及び天井下地材に固定されるため、ブレースを介して振動（音）が伝播することとなり、防振性が低下していた。 Conventionally, as a ceiling foundation structure, for example, a structure as shown in Patent Document 1 (FIG. 16) is known. In this ceiling, vibration (sound) is suppressed by vibration-proof hangers interposed in the hanging material hanging from the ceiling slab, and the brace that is inclined between the ceiling slab and the ceiling base material is used for earthquakes. Suppresses the generated ceiling shaking. However, since the brace is fixed to the suspension material and the ceiling base material, vibration (sound) is propagated through the brace, and the vibration-proof property is lowered.

そこで、同文献（図１）では、ブレースの中間部に防振部材を介在させた構造を採用している。しかしながら、天井面に水平荷重が生じた場合、防振部材で座屈が生じやすく、耐震性能を十分に確保することが困難な場合があった。 Therefore, in the same document (FIG. 1), a structure in which a vibration isolating member is interposed in an intermediate portion of the brace is adopted. However, when a horizontal load is generated on the ceiling surface, buckling is likely to occur in the vibration isolating member, and it may be difficult to ensure sufficient seismic performance.

かかる従来の実情に鑑みて、本発明は、簡素な構造でありながら防振性及び耐震性の向上を両立する接続金具を提供することを目的とする。 In view of such a conventional situation, an object of the present invention is to provide a connection fitting that has both a simple structure and an improvement in vibration resistance and vibration resistance.

上記目的を達成するため、本発明に係る接続金具の特徴は、天井スラブと天井下地材との間で傾斜して設けられるブレースと前記天井下地材とを接続する構成において、前記天井下地材に固定される第一固定部材と、前記天井下地材を構成する野縁及び野縁受の一方の長手方向に沿って設けられ前記ブレースの下端を挟持する一対のブレース受材と、前記一対のブレース受材を連結固定する第二固定部材と、本体部と前記第一固定部材の貫通孔に係合する係合部とを有する防振ゴムと、前記防振ゴム、前記第一固定部材及び前記第二固定部材を貫通しこれら部材を接続する接続部材を備え、前記防振ゴムが係合する前記第一固定部材に前記本体部の水平方向への変形を制限する変形制限手段を設けたことにある。 In order to achieve the above object, the connection metal fitting according to the present invention is characterized in that, in the configuration in which a brace provided inclined between a ceiling slab and a ceiling base material is connected to the ceiling base material, the ceiling base material A first fixing member to be fixed, a pair of brace receiving materials provided along one longitudinal direction of a field edge and a field edge receiving the ceiling base material, and sandwiching a lower end of the brace, and the pair of braces An anti-vibration rubber having a second fixing member for connecting and fixing the receiving material, an engagement portion engaging with a through hole of the first fixing member, the anti-vibration rubber, the first fixing member, and the A connecting member that passes through the second fixing member and connects these members is provided, and the first fixing member that engages with the anti-vibration rubber is provided with a deformation limiting means that limits deformation of the main body portion in the horizontal direction. It is in.

上記構成によれば、天井下地材に固定される第一固定部材と、天井下地材を構成する野縁及び野縁受の一方の長手方向に沿って設けられブレースの下端を挟持する一対のブレース受材を連結固定する第二固定部材とは、防振ゴムを介して接続部材で接続されているので、防振ゴムによって絶縁が確保される。これにより、地震等によって生じる天井の揺れがブレースへ伝播されることを防止でき、防振性を確保することができる。しかも、防振ゴムが係合する第一固定部材に本体部の水平方向への変形を制限する変形制限手段を設けているので、地震等によって天井面に生じる水平荷重により、防振ゴムの本体部が水平方向へ変形すると、変形制限手段が防振ゴムの変形を抑制する。この変形抑制によって、防振ゴムには反発力が発生し、接続部材を元の位置に押し戻すよう作用する。従って、第一、第二固定部材間での絶縁が維持されると共に、接続部材は水平荷重に対抗できるので、耐震性及び防振性の両立が可能となる。 According to the above configuration, the first fixing member fixed to the ceiling base material and the pair of braces provided along one longitudinal direction of the field edge and the field edge constituting the ceiling base material and sandwiching the lower end of the brace Since the second fixing member for connecting and fixing the receiving member is connected by a connecting member via a vibration isolating rubber, insulation is ensured by the vibration isolating rubber. Thereby, it is possible to prevent the shaking of the ceiling caused by an earthquake or the like from being propagated to the brace, and to ensure the vibration proof property. In addition, since the first fixing member with which the anti-vibration rubber is engaged is provided with deformation limiting means for limiting the deformation of the main body in the horizontal direction, the main body of the anti-vibration rubber is caused by the horizontal load generated on the ceiling surface due to an earthquake or the like. When the portion is deformed in the horizontal direction, the deformation limiting means suppresses deformation of the vibration isolating rubber. Due to this deformation suppression, a repulsive force is generated in the vibration-proof rubber and acts to push the connecting member back to the original position. Accordingly, the insulation between the first and second fixing members is maintained, and the connecting member can withstand a horizontal load, so that both earthquake resistance and vibration proofing can be achieved.

係る場合、前記本体部の上面と前記第一固定部材の上面との間にクリアランスを形成するとよい。このクリアランスにより、天井材を接続した際に天井材の自重による過度の変形を抑制でき、防振性の低下を防止することができる。 In such a case, a clearance may be formed between the upper surface of the main body portion and the upper surface of the first fixing member. With this clearance, when the ceiling material is connected, excessive deformation due to the weight of the ceiling material can be suppressed, and deterioration of the vibration proof property can be prevented.

前記第一固定部材は、前記本体部を挟んで対向する一対の壁部を有し、前記変形制限手段は、前記一対の壁部と前記一対の壁部の間で前記本体部に当接する当接部材とにより構成されるようにしてもよい。係る場合、前記当接部材は、前記第一固定部材の上面に前記接続部材を挟んで一対取り付けられる長尺部材であってもよく、前記第一固定部材の側面に前記接続部材を挟んで一対取り付けられる長尺部材であってもよい。また、前記変形制限手段は、前記防振ゴムを取り囲むリング状部材により構成されるようにしてもよい。さらに、前記当接部材は、ボルトとこのボルトに締結される長ナットより構成されてもよい。 The first fixing member has a pair of wall portions opposed to each other with the main body portion interposed therebetween, and the deformation limiting means contacts the main body portion between the pair of wall portions and the pair of wall portions. You may make it comprise with a contact member. In this case, the contact member may be a long member attached to the upper surface of the first fixing member with the connection member interposed therebetween, and a pair of the contact members sandwiching the connection member on the side surface of the first fixing member. It may be a long member to be attached. Further, the deformation limiting means may be constituted by a ring-shaped member surrounding the vibration-proof rubber. Further, the contact member may be constituted by a bolt and a long nut fastened to the bolt.

上記本発明に係る接続金具の特徴によれば、簡素な構造でありながら防振性及び耐震性の向上を両立することが可能となった。 According to the characteristics of the connection fitting according to the present invention, it is possible to achieve both improvement in vibration proofing and earthquake resistance while having a simple structure.

次に、図１〜図５を参照しながら、本発明の第一実施形態についてさらに詳しく説明する。
本発明の第一実施形態に係る接続金具１０は、例えば図１に示す如き天井下地構造１に用いられ、防振耐震ハンガーとして機能する。この天井下地構造１は、大略、天井スラブ２から垂下させた吊材としての吊ボルト３と、天井仕上材４を支持する天井下地材５と、吊ボルト３と天井下地材５とを連結するハンガー６及び防振耐震ハンガー１０と、吊ボルト３と天井下地材５との間で傾斜状に架け渡されるブレース７とを備える。 Next, the first embodiment of the present invention will be described in more detail with reference to FIGS.
The connection fitting 10 according to the first embodiment of the present invention is used for a ceiling base structure 1 as shown in FIG. 1, for example, and functions as a vibration-proof and earthquake-resistant hanger. This ceiling foundation structure 1 generally connects a suspension bolt 3 as a suspension material suspended from a ceiling slab 2, a ceiling foundation material 5 that supports the ceiling finishing material 4, and the suspension bolt 3 and the ceiling foundation material 5. A hanger 6 and a vibration-proof and earthquake-resistant hanger 10 and a brace 7 that is slanted between the suspension bolt 3 and the ceiling base material 5 are provided.

天井下地材５は、天井仕上材４を取り付け固定する野縁５ａと野縁５ａ上で配設される野縁受５ｂとが格子状に組み付けられて構成されている。ハンガー６及び防振耐震ハンガー１０は、例えば、野縁５ａの長手方向Ｘに対し交互に設けられ、天井仕上材４及び天井下地材５を水平に支持する。なお、ハンガー６の上部には公知の防振連結部材９が設けられ、当該連結部分においても防振性が確保されている。 The ceiling base material 5 is configured by assembling a field edge 5a for attaching and fixing the ceiling finishing material 4 and a field edge receiver 5b disposed on the field edge 5a in a lattice shape. The hangers 6 and the vibration-proof and earthquake-proof hangers 10 are provided alternately with respect to the longitudinal direction X of the field edge 5a, for example, and support the ceiling finishing material 4 and the ceiling base material 5 horizontally. A known anti-vibration connecting member 9 is provided on the top of the hanger 6, and the anti-vibration property is also ensured at the connecting portion.

ここで、本発明に係る防振耐震ハンガー１０は、図１に示すように、天井スラブ２から垂下させた吊ボルト３と天井仕上材４を支持する天井下地材５とを連結すると共に、ブレース材７の下端７ａを取り付け固定するものである。なお、ブレース材７の上端７ｂは取付金具８を介して吊ボルト３の天井スラブ２近傍に取り付けられる。この防振耐震ハンガー１０は、図２〜４に示すように、大略、野縁受５ｂを取り付け固定するハンガー部材２０と、吊ボルト３とハンガー部材２０と連結する連結部材３０と、連結部材３０に係合する防振ゴム４０と、ハンガー部材２０、連結部材３０及び防振ゴム４０を貫通しこれら部材２０，３０，４０を接続する接続部材５０を備える。本実施形態において、ハンガー部材２０が第一固定部材として機能し、連結部材３０が第二固定部材として機能する。 Here, the vibration-proof and earthquake-resistant hanger 10 according to the present invention connects the suspension bolt 3 suspended from the ceiling slab 2 and the ceiling base material 5 supporting the ceiling finishing material 4 as shown in FIG. The lower end 7a of the material 7 is attached and fixed. The upper end 7b of the brace material 7 is attached to the vicinity of the ceiling slab 2 of the suspension bolt 3 via the attachment fitting 8. As shown in FIGS. 2 to 4, the vibration-proof and earthquake-resistant hanger 10 is roughly a hanger member 20 for attaching and fixing the field receiver 5 b, a connecting member 30 for connecting the suspension bolt 3 and the hanger member 20, and a connecting member 30. And a connecting member 50 that penetrates through the hanger member 20, the connecting member 30, and the anti-vibration rubber 40 and connects these members 20, 30, and 40. In the present embodiment, the hanger member 20 functions as a first fixing member, and the connecting member 30 functions as a second fixing member.

図２〜４に示すように、ハンガー部材２０は、大略、野縁受５ｂを保持するハンガー本体２１と、ハンガー本体２１の上端を略垂直に折り曲げて形成した折曲部２２とを有する。ハンガー本体２１は、野縁受５ｂを受け入れる受入部２３と、野縁受５ｂを固定するボルト等の固定具２４を取り付ける取付孔２５とを備える。また、折曲部２２には、接続部材５０を貫通させる貫通孔２６が形成されている。 As shown in FIGS. 2 to 4, the hanger member 20 generally includes a hanger body 21 that holds the field receiver 5 b and a bent portion 22 that is formed by bending the upper end of the hanger body 21 substantially vertically. The hanger body 21 includes a receiving portion 23 that receives the field receiver 5b, and a mounting hole 25 for attaching a fixture 24 such as a bolt that fixes the field receiver 5b. Further, the bent portion 22 is formed with a through hole 26 through which the connecting member 50 passes.

図２〜４に示すように、連結部材３０は、大略、平行する上部３１及び下部３２と、上部３１及び下部３２と略直交し野縁５ａの長手方向Ｘで対向する一対の壁部３３，３３と、各壁部３３に野縁５ａの長手方向Ｘへ向けて垂設されたブレース取付部３４とを有する。ブレース取付部３４には、ブレース７の下端７ａが固定具としてのビス３０ｘにより取り付け固定される。これにより、ブレース７は連結部材３０に対し対称配置可能となり、ブレース７の下端７ａを互いに近接配置することができる。近接配置することで、地震等による水平荷重Ｆが効率よくブレース７，７間で伝達され、耐震性能がさらに向上する。 As shown in FIGS. 2 to 4, the connecting member 30 includes an upper portion 31 and a lower portion 32 that are substantially parallel to each other, and a pair of wall portions 33 that are substantially orthogonal to the upper portion 31 and the lower portion 32 and face each other in the longitudinal direction X of the field edge 5a. 33 and a brace mounting portion 34 that is suspended from each wall portion 33 in the longitudinal direction X of the field edge 5a. The lower end 7a of the brace 7 is attached and fixed to the brace attaching portion 34 with screws 30x as a fixture. Thereby, the brace 7 can be arranged symmetrically with respect to the connecting member 30, and the lower ends 7a of the braces 7 can be arranged close to each other. By arranging them close to each other, the horizontal load F caused by an earthquake or the like is efficiently transmitted between the braces 7 and 7, and the seismic performance is further improved.

本実施形態において、連結部材３０は、例えば板状材を屈曲させて一対作製された部材を対向させて上部３１及び下部３２を重ね合わせて溶接等により固着させて形成される。よって、本実施形態では、壁部３３とブレース取付部３４とは一体である。上部３１には吊ボルト３を貫通させる貫通孔３１ａが設けられている。 In the present embodiment, the connecting member 30 is formed, for example, by bending a plate-like material and making a pair of members face each other, overlapping the upper portion 31 and the lower portion 32 and fixing them by welding or the like. Therefore, in this embodiment, the wall part 33 and the brace attaching part 34 are integral. The upper portion 31 is provided with a through hole 31a through which the suspension bolt 3 is passed.

連結部材３０の底面となる下部３２は、図２〜４に示すように、略正方形の下中央部３２ａと、その下中央部３２ａから野縁受５ｂの長手方向Ｙに向けて突出する一対の延長部３２ｂ，３２ｂを有する。下中央部３２ａには、後述の防振ゴム４０の係合部４２が係合する貫通孔３２ｃが設けられている。また、この下部３２には、貫通孔３２ｃを挟んで野縁受５ｂの長手方向Ｙに沿って突出部３５を取り付ける取付孔３２ｄが対称に設けられている。本実施形態において、突出部３５は、ボルト３５ａと長ナット３５ｂより構成されている。 2-4, the lower part 32 used as the bottom face of the connection member 30 has a substantially square lower center part 32a and a pair of protrusions projecting from the lower center part 32a toward the longitudinal direction Y of the field receiver 5b. It has the extension parts 32b and 32b. The lower center portion 32a is provided with a through hole 32c into which an engaging portion 42 of a vibration isolating rubber 40 described later is engaged. The lower portion 32 is provided with a mounting hole 32d for attaching the protruding portion 35 along the longitudinal direction Y of the field receiver 5b with the through hole 32c interposed therebetween. In this embodiment, the protrusion part 35 is comprised from the volt | bolt 35a and the long nut 35b.

図３〜５に示すように、防振ゴム４０は、円柱状の本体部４１と、この本体部４１から鉛直方向Ｚに向けて突出し連結部材３０の貫通孔３２ｃに係合する係合部４２とを備える。本体部４１及び係合部４２の中央部には、接続部材５０を貫通させる貫通孔４３が鉛直方向Ｚに沿って設けられ、貫通孔４３と接続部材５０との間には隙間４４が形成される。これにより、ハンガー部材２０と連結部材３０との間の絶縁を確保している。また、ハンガー部材２０の折曲部２２と連結部材３０の下部３２との間には、係合部４２を取り囲む第二の防振ゴム４５が設けられ、ハンガー部材２０と連結部材３０の間で生じる鉛直方向Ｚの振動を吸収し、防振性をさらに向上させる。 As shown in FIGS. 3 to 5, the anti-vibration rubber 40 includes a columnar main body 41 and an engaging portion 42 that protrudes from the main body 41 in the vertical direction Z and engages with the through hole 32 c of the connecting member 30. With. A through-hole 43 through which the connection member 50 passes is provided along the vertical direction Z in the center of the main body 41 and the engagement portion 42, and a gap 44 is formed between the through-hole 43 and the connection member 50. The Thereby, the insulation between the hanger member 20 and the connection member 30 is ensured. Further, a second anti-vibration rubber 45 surrounding the engaging portion 42 is provided between the bent portion 22 of the hanger member 20 and the lower portion 32 of the connecting member 30, and between the hanger member 20 and the connecting member 30. Absorbs the vibration in the vertical direction Z that occurs, further improving the vibration isolation.

ここで、防振耐震ハンガー１０の組み付けについて説明する。
上述の如く構成されたハンガー部材２０、連結部材３０及び防振ゴム４０には、図３〜５に示すように、接続部材としてのボルト５０が貫通されナット５１によって鉛直方向Ｚに沿って接続固定される。この際、ボルト５０は水平荷重Ｆに対抗することとなる。また、防振ゴム４０の本体部４１は、連結部材３０の下部３２上で壁部３３，３３の間に配置され、ブレース７は連結部材３０のブレース取付部３４に取り付けられる。 Here, the assembly of the vibration-proof and earthquake-resistant hanger 10 will be described.
As shown in FIGS. 3 to 5, the hanger member 20, the connecting member 30, and the anti-vibration rubber 40 configured as described above are penetrated by bolts 50 as connecting members and fixedly connected along the vertical direction Z by nuts 51. Is done. At this time, the bolt 50 opposes the horizontal load F. The main body 41 of the vibration isolating rubber 40 is disposed between the walls 33 and 33 on the lower portion 32 of the connecting member 30, and the brace 7 is attached to the brace attaching portion 34 of the connecting member 30.

そして、図５に示すように、防振ゴム４０の本体部４１は、連結部材３０の壁部３３に対し隙間をおいて近接配置されている。また、突出部３５の長ナット３５ｂも、本体部４１に対し隙間をおいて近接配置されている。天井面Ｃに水平荷重Ｆが生じると、その水平荷重Ｆによってボルト５０が本体部４１を押圧して、本体部４１を変形させる。ここで、野縁長手方向Ｘへの変形成分は、本体部４１に近接配置された連結部材３０の壁部３３により抑制される。他方、野縁受長手方向Ｙへの変形成分は、本体部４１に近接配置された長ナット３５ｂにより抑制される。本体部４１が長ナット３５ｂ及び／又は壁部３３に当接することによって、本体部４１には各変形成分に対抗する反発力が生じ、この反発力がボルト５０を貫通孔４３の中心に押し戻す。よって、ハンガー部材２０と連結部材３０との間で絶縁が維持されると共に、ボルト５０は水平荷重Ｆに対抗できる。 And as shown in FIG. 5, the main-body part 41 of the anti-vibration rubber 40 is arrange | positioned closely with respect to the wall part 33 of the connection member 30 with a clearance gap. Further, the long nut 35 b of the protruding portion 35 is also arranged in close proximity to the main body portion 41 with a gap. When the horizontal load F is generated on the ceiling surface C, the bolt 50 presses the main body 41 by the horizontal load F, and the main body 41 is deformed. Here, the deformation component in the field edge longitudinal direction X is suppressed by the wall portion 33 of the connecting member 30 disposed close to the main body portion 41. On the other hand, the deformation component in the field edge receiving longitudinal direction Y is suppressed by the long nut 35 b disposed close to the main body portion 41. When the main body 41 abuts against the long nut 35 b and / or the wall 33, a repulsive force that opposes each deformation component is generated in the main body 41, and this repulsive force pushes the bolt 50 back to the center of the through hole 43. Therefore, insulation is maintained between the hanger member 20 and the connecting member 30, and the bolt 50 can counter the horizontal load F.

このように、第一実施形態では、野縁長手方向Ｘで対向する一対の壁部３３，３３と、野縁受長手方向Ｙで対向する一対の突出部（長ナット）３５ｂ，３５ｂとが、防振ゴム４０の本体部４１の水平方向への変形を制限する変形制限手段６０として機能し、耐震性及び防振性の双方を確保することが可能となる。 Thus, in the first embodiment, the pair of wall portions 33 and 33 that are opposed in the field edge longitudinal direction X and the pair of protrusions (long nuts) 35b and 35b that are opposed in the field edge longitudinal direction Y are The anti-vibration rubber 40 functions as a deformation limiting means 60 for limiting the deformation of the main body 41 in the horizontal direction, and it is possible to ensure both earthquake resistance and vibration isolation.

次に、図６〜９ｆを参照しがなら、上記第一実施形態の連結部材３０の改変例について説明する。
図６（ａ）に示す第１改変例における連結部材３０Ａは、一対の壁部３３，３３を有する箱形を呈し、一方の開口部にブレース取付部３４が垂設されている。上述のように、板状材を屈曲させて一対作製した部材を対向させて溶接等により形成しなくても構わない。この例では、突出部としてピン３５ｃを下部３２に鉛直方向Ｚに向けて立設し、一対の壁部３３，３３及び一対のピン３５ｃ，３５ｃにより変形制限手段６０を構成している。なお、このピン３５ｃは、下部３２と一体に形成してもよく、別体として形成し溶接等で溶着させてもよい。 Next, referring to FIGS. 6 to 9f, a modified example of the connecting member 30 of the first embodiment will be described.
The connecting member 30A in the first modification shown in FIG. 6A has a box shape having a pair of wall portions 33, 33, and a brace attaching portion 34 is suspended from one opening. As described above, it is not necessary to form a pair of members made by bending a plate-like material so as to be opposed to each other by welding or the like. In this example, a pin 35c is erected on the lower portion 32 in the vertical direction Z as a protruding portion, and the deformation limiting means 60 is configured by the pair of wall portions 33, 33 and the pair of pins 35c, 35c. The pin 35c may be formed integrally with the lower portion 32, or may be formed separately and welded by welding or the like.

図６（ｂ）に示す第２改変例における連結部材３０Ｂは、一対の壁部３３，３３に互いに直交し且つ鉛直方向Ｚに沿う第二壁部３３ａを設けている。この例では、一対の壁部３３，３３、第二壁部３３ａ及びピン３５ｃにより変形制限手段６０を構成している。もちろん、ピン３５ｃに代えて長ナット３５ｂでも構わない。 In the second modification example shown in FIG. 6B, the connecting member 30 </ b> B is provided with a second wall portion 33 a that is orthogonal to the pair of wall portions 33 and 33 and that extends along the vertical direction Z. In this example, the deformation limiting means 60 is configured by the pair of wall portions 33, 33, the second wall portion 33a, and the pin 35c. Of course, a long nut 35b may be used instead of the pin 35c.

The lip portion 730 is fixed to the lower flange 5b1 of the field edge receiver 5b with, for example, a screw 700x as a fixture. The width of the pair of flanges 720 and 720 (distance between the inner surfaces) is substantially equal to the width of the pair of flanges 220 and 220 of the bracket 200 (distance between the outer surfaces of the flanges 220).

ここで、接続金具１００の組み付けについて説明する。
上述の如く構成されたブラケット２００、固定板４００及び防振ゴム５００には、図１０〜１２に示すように、接続部材としてのボルト６００が貫通されナット６１０によって鉛直方向Ｚに沿って接続固定される。この際、防振ゴム５００の本体部５１０は、ブラケット２００の収容部２３０に配置される。また、本体部５１０とブラケット２００のウェブ２１０との間には、クリアランス１２０が形成される。クリアランス１２０を形成しておくことで、吊材３により吊り下げ支持される天井材の自重による防振ゴム５００の過度な変形を抑制し、防振性の低下を防止する。 Here, the assembly of the connection fitting 100 will be described.
As shown in FIGS. 10 to 12, a bolt 600 as a connecting member is passed through the bracket 200, the fixing plate 400, and the anti-vibration rubber 500 configured as described above, and is connected and fixed along the vertical direction Z by a nut 610. The At this time, the main body 510 of the anti-vibration rubber 500 is disposed in the housing portion 230 of the bracket 200. A clearance 120 is formed between the main body 510 and the web 210 of the bracket 200. By forming the clearance 120, excessive deformation of the vibration-proof rubber 500 due to the weight of the ceiling material supported by the suspension member 3 is suppressed, and the deterioration of the vibration-proof property is prevented.

ボルト６００は、ブレース受材３００の長手方向（野縁長手方向Ｘ）両端部に間隔をおいて固定され、水平荷重Ｆに対抗する。ブラケット２００には野縁補強材７００が嵌入され、対向するブラケット２００のフランジ２２０と野縁補強材７００のフランジ７２０とがビス７００ｘで固定止めされる。また、野縁補強材７００のリップ部７３０と野縁受５ｂの下フランジ５ｂ１とがビス７００ｘで固定止めされる。これにより、水平荷重Ｆを野縁補強材７００からブラケット２００及びボルト６００を介してブレース７まで効率よく伝達させることができる。 The bolts 600 are fixed at both ends in the longitudinal direction (field edge longitudinal direction X) of the brace receiving member 300 with an interval therebetween, and resist the horizontal load F. The edge reinforcing member 700 is fitted into the bracket 200, and the flange 220 of the bracket 200 and the flange 720 of the edge reinforcing member 700 which are opposed to each other are fixed by screws 700x. Further, the lip portion 730 of the field edge reinforcing member 700 and the lower flange 5b1 of the field edge receiver 5b are fixed and fixed by screws 700x. Thereby, the horizontal load F can be efficiently transmitted from the field reinforcement member 700 to the brace 7 via the bracket 200 and the bolt 600.

さらに、ブラケット２００及び固定板４００の幅方向（野縁受長手方向Ｙ）中央部には貫通孔２１０ａ，４２０が位置し、且つ貫通孔４２０は空間１１０の幅方向（野縁受長手方向Ｙ）中央に位置する。また、ブレース７は、その側面と対向するブレース受材３００のウェブ３１０とがビス３００ｘで固定止めされる。そして、ハンガー１４０は、空間１１０内で且つ固定板４００，４００の間に配置される。この位置関係により、図１１に示すように、野縁補強材７００の中心軸（野縁方向Ｘに沿う水平荷重の中心）、ブレース７の中心軸、吊材３の中心軸及び接続部材６００の中心軸は、軸Ａ１上で全て一致する。従って、軸ずれによる各部材のねじれ等の変形を防止でき、天井下地構造全体の耐震性が向上する。 Furthermore, through holes 210a and 420 are located in the center of the width direction (field edge receiving longitudinal direction Y) of the bracket 200 and the fixing plate 400, and the through hole 420 is formed in the width direction of the space 110 (field edge receiving longitudinal direction Y). Located in the center. Further, the brace 7 is secured to the web 310 of the brace receiving material 300 facing the side surface with screws 300x. The hanger 140 is disposed in the space 110 and between the fixed plates 400 and 400. With this positional relationship, as shown in FIG. 11, the center axis of the field edge reinforcing member 700 (the center of the horizontal load along the field edge direction X), the center axis of the brace 7, the center axis of the suspension member 3, and the connection member 600. The central axes all coincide on the axis A1. Therefore, deformation such as torsion of each member due to axial deviation can be prevented, and the earthquake resistance of the entire ceiling base structure is improved.

しかも、図１２に示すように、防振ゴム５００の本体部５１０は、ブラケット２００のフランジ２２０に僅かに隙間をおいて近接配置されている。また、突出部２４０の長ナット２４０ｂは、本体部５１０に接触して配置されている。天井面Ｃに水平荷重Ｆが生じると、その水平荷重Ｆによってボルト６００が本体部５１０を押圧して、本体部５１０を変形させる。ここで、野縁長手方向Ｘへの変形成分は、本体部５１０に接触配置された長ナット２４０ｂにより抑制される。他方、野縁受長手方向Ｙへの変形成分は、本体部５１０に近接されたブラケット２００のフランジ２２０により抑制される。本体部５１０が長ナット２４０ｂ及び／又はフランジ２２０に当接することによって、本体部５１０には各変形成分に対抗する反発力が生じる。この反発力によって、ボルト６００は各貫通孔の中心に押し戻されることとなり、絶縁が維持されると共に軸ずれが抑制される。従って、防振性及び耐震性が確保される。 Moreover, as shown in FIG. 12, the main body 510 of the anti-vibration rubber 500 is disposed close to the flange 220 of the bracket 200 with a slight gap. Further, the long nut 240 b of the protruding portion 240 is disposed in contact with the main body portion 510. When the horizontal load F is generated on the ceiling surface C, the bolt 600 presses the main body 510 by the horizontal load F, and the main body 510 is deformed. Here, the deformation component in the field edge longitudinal direction X is suppressed by the long nut 240 b disposed in contact with the main body 510. On the other hand, a deformation component in the field receiving longitudinal direction Y is suppressed by the flange 220 of the bracket 200 close to the main body 510. When the main body 510 comes into contact with the long nut 240b and / or the flange 220, a repulsive force that opposes each deformation component is generated in the main body 510. By this repulsive force, the bolt 600 is pushed back to the center of each through hole, and insulation is maintained and axial deviation is suppressed. Therefore, vibration proofing and earthquake resistance are ensured.

このように、第二実施形態では、野縁長手方向Ｘで対向する一対の突出部（長ナット）２４０ｂ，２４０ｂと、野縁受長手方向Ｙで対向する一対のフランジ２２０，２２０とが、防振ゴム５００の本体部５１０の水平方向への変形を制限する変形制限手段６０として機能し、耐震性及び防振性の双方を確保することが可能となる。 Thus, in the second embodiment, the pair of protrusions (long nuts) 240b and 240b that are opposed in the field edge longitudinal direction X and the pair of flanges 220 and 220 that are opposed in the field edge longitudinal direction Y are prevented. It functions as the deformation limiting means 60 that limits the deformation of the main body 510 of the vibration rubber 500 in the horizontal direction, and it is possible to ensure both earthquake resistance and vibration isolation.
